ELECTROMAGNETIC VALVE.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed January 12, 1904:. Serial No. 188,786.

T at whom it may concern: 1

Be it known that I, IsAAo Gr. WATERMAN, a citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, have invented new and useful Improvements in Electromagnetic Valves,

of which the following is a specification.

This invention relates to electromagnetic valves, and more particularly to waste-valves.

The present invention relates to the general type of waste-valve set forth in my copending application,filed September 9, 1903, Serial No. 172,489, embodying the idea of using a single solenoid or coil around the waste-pipe of any receptacle, such as a lavatory or bathtub, and a spring-pressed armature slidable in or on the pipe and controlled by the solenoid, a spring-seated waste-valve, a cam cooperating with the waste-valve, and a pawl and ratchet-Wheel for operating the cam; but the improvements embodied in the present invention are adaptable for use not only in connection with the type of valve of the aforesaid application,but also on the valves claimed in other applications heretofore filed by me, instances of which are my applications, filed July 9, 1903, Serial No. 164:,888, and Serial No. 171,215, filed August 29, 1903, and other valve applications executed of evendate with the present application.

The object of the present invention is the provision of improvements supplemental to the valve-operating mechanism proper, whereby the valve will always be brought to the exact position to which it should be moved to open the valve to its full extent or to completely close said valve, whether or not the valveoperating member moves its predetermined distance in operation.

The invention contemplates the use of novel supplemental means for adjusting the valve on the operation thereof to the proper position, so that if only partly opened or only partly closed by the action of the valve-operatingmember such incomplete movement of the valve will be completed and the fault rectified automatically.

The invention is set forth in detail hereinafter and recited in the appended claims.

In the accompanying drawings, Figure 1 is a sectional elevation. Fig. 2, an enlarged View of theinvention, partly in section; Fig. 3, a similar view showing the different parts in action and the cam and valve-stem in full lines; and Fig. A, an exterior view of the pipe-section with the armature and solenoid in section, showing the cut-out portion of the pipe-section and illustrating a modified form of packing.

A lavatory bowl or basin is shown at 1, having the overflow-channel 2 and valve seat 3 for waste-valve 4, and 5 is the waste-pipe section, suitably coupled to the basin 1 at 6. The waste-valve stem 7 operates through a stationary cross piece or guide 7 and carries a guide 8, movable with said stem, which is suitably guided in the pipe 5 to prevent it from turning. The waste-valve has a normal tendency to close on account of the interposition of a coil-spring 9 between guide 8 and cross-piece 7, and at the lower end of the stem is a roller 10.

Jon rnaled in the pipe-section 5 transversely is a shaft 11, suitably packed at 12, which has secured thereto a cam-wheel 13, having depressions 1 1 at the ends of its minor axis and depressions at the ends of itsv major axis. The roller 10 bears on the cam-wheel and is adapted to snap into and out of the different depressions as the cam-wheel turns to thereby open and close the waste-valve. I

The outer face of the pipe-section 5 is cut away at 16, and the shaft 11 is there provided with a rigidlyrsecured ratchet-wheel 17 ,whose teeth are arranged in four sets of three teeth.

each. A spring-pressed pawl 18, pivoted to the pipe-section, prevents backward turning of the ratchet-wheel and valve.

Screwed on the pipe-section 5 is a nut 19, which supports a shell 20, packing 21 being used between the shell and nut, around which is a solenoid 22, held against a shoulder 23 on the pipe-section 5.

Surrounding the shell and slidable thereon is a tubular armature 2 1, which is pressed in one direction by a coil-spring 25.

In Fig. 1 a modification of the above construction exists in the use of packing 26 and 'a washer 2'7, interposed between the spring when pressed back again by the spring 25. Pivoted at 32 to the armature is a pawl 33, having three teeth 34, adapted to engage the nearest set of the teeth on the ratchet-wheel when the armature is attracted by the solenoid. This pawl is pressed into engagement with the ratchet-wheel by a spring 35 on the armature.

The supply of current to the solenoid may be controlled by any suitable switch; but any one of a series of temporary contact-switches set forth in my Patents Nos. 775,016, 775,053, 775,055, dated November 15, 1904, is particularly adapted for this purpose, as the solenoid is designed to actuate the armature on temporary electrical energization. When the solenoid is energized, the armature is attracted thereinto, and the pawl turns the ratchet- Wheel a quarter-revolution, opening or closing the waste-valve according to the prior position of the latter. i/Vhen the'armature is thus actuated, the shoulder 31 strikes against the nut 28, and if the valve has not been positioned correctly the engagement of the nut and said shoulder causes the valve to be posi:

tioned exactly correct. When the armature is returned to normal position by the spring 25, the shoulder 30 strikes the nut 28, and if the valve was not correctly positioned previously by the shoulder 31 the engagement of shoulder 30 and nut 28 properly positions the valve.

It will be understood that I do not limit myself to the use of the valve rectifying or adjusting means in connection with a valve of the type set forth in the present application, as I am well aware that the said valve adjusting or rectifying means can be used in connection with rotary valves of different types and the valves of my application heretofore enumerated herein.

In my application, Serial No. 188,783, I have disclosed a valve operated by a toothed wheel and a toothed actuating member cooperating with said toothed wheel and adapted to play between predetermined limits.
